Question 1 10 pts A conducting sphere of radius 10 cm is surrounded by a uniformly charged, hollow, conducting spherical shell with inner radius 20 cm and outer radius 30 cm. The conducting sphere has a net charge of -50 mC and the hollow conducting shell has a net charge of +50 mC. a) Determine the Electric Field at all points in space. b) Using the Electric Field found in part a, find the Electric Potential at all points in space. c) Determine the Work needed to move a -50 nC point charge from infinity to a point 33 cm away from the center of the conducting sphere
